Chapter

Introducing the SAN I/O Module

The Brocade 4424 is a 24-port Fibre Channel module with 8 external ports and 16 internal ports
designed for installation in a Dell PowerEdge M1000e Blade Server Enclosure. The product ships
with 12 ports enabled and can be upgraded to 24 ports through Ports on Demand (POD) licensing.
These ports support link speeds up to 4Gbit/sec.

Dual function and access gateway configurations

The SAN I/O Module ships in one of two configurations:

• Dual Function configuration. In this configuration, the SAN I/O Module operates in Standard

Full Fabric Switch mode by default. The module can also operate in Access Gateway mode.

• Access Gateway configuration. In this configuration the SAN I/O Module operates exclusively in

Access Gateway mode. Access Gateway simplifies SAN deployment by using NPIV. NPIV
provides Fibre Channel switch functions that improve SAN I/O Module scalability,
manageability, and interoperability. For more information on Access Gateway, refer to the
following:

- For a list of SAN I/O Module F_Ports mapped to N_Ports in the SAN I/O Module as shipped

from the factory, refer to “Access Gateway Mode default port mapping” on page 25.

- For general information and details on using Access Gateway, refer to the Brocade Access

Gateway Administrator’s Guide.

- Since Access Gateway relies on NPIV technology for its connection to the edge fabric you

may have to prepare the edge fabric before connecting it to Access Gateway. Please refer
to the SAN TECH NOTE – Preparing to Install the Brocade Access Gateway for specific
instructions.

1

NOTE

When shipped in Access Gateway configuration, a Switch (Fabric) license is required to operate the
module in Standard Full Fabric Switch mode.

NOTE

Access Gateway cannot be connected directly into an array; it requires a fabric to support NPIV.

Determining module configuration

The factory configuration type is identified by the part number on a label attached to the module.
Refer to Figure 3 on page 5 for label location.

• If the part number is DL-4424-0001, then the SAN I/O Module is configured in Standard Full

Fabric Switch mode. Note that Full Fabric Switch mode is the default setting when shipped
from the factory. Access Gateway mode can also be enabled on this module.

Features

• If the part number is DL-4424-0002, then the SAN I/O Module is configured to run exclusively

in Access Gateway mode. To operate in Full Fabric Switch mode, you must have a Switch
license.

You may also use the CLI licenseshow command to determine whether the module is Dual Function
(Switch/Access Gateway), or single-function Access Gateway. This command displays current
license keys, along with a list of licensed products enabled by these keys. A Dual Function
(Switch/Access Gateway) module should have a “Fabric license” in the command output.

Features available on the SAN I/O Module depend on whether the module is configured in Access
Gateway or Standard Full Fabric Switch mode.

Full Fabric Switch mode

The SAN I/O Module has the following features:

• Up to 8 external autosensing (1, 2, and 4 Gbit/sec) Fibre Channel ports. These are universal

and self-configuring ports are capable of becoming one of the following port types:

- F_Port (fabric enabled)

- FL_Port (fabric loop enabled)

- E_Port (expansion port)

These ports are capable of Brocade ISL Trunking with appropriate licensing.

• Up to 16 internal backplane F_Ports. Each port is capable of automatic negotiation to the

highest common speed of all connected devices at 4 Gbit/sec.

• Dynamic ports on demand, which allows any port to be activated as needed based on available

licenses.

• Frame filtering that augments the hardware zoning capabilities of the Brocade ASIC, which

implements hardware zoning at the port level of the SAN I/O Module.

• Brocade ASIC expanded capabilities, including World Wide Name (WWN) and device-level

zoning.

• Hardware zoning, implemented by means of a firmware-accessible table per output port.

• Extensive diagnostics and monitoring capabilities.

• Unicast and broadcast data traffic support.

• Up to eight SWL small form-factor pluggable (SFP) optical transceivers.

Ports on Demand (POD)

The SAN I/O Module ships with 12 active ports. You can allocate a POD license to activate 12
additional ports. The SAN I/O Module supports two licensing methods: static and dynamic (module
default).

• For Dynamic POD, 12 licenses are available for the first 12 active ports. Ports 17 and 18 are

licensed at the factory. The remaining 10 licenses are assigned to active ports as required.
Once licenses are issued, they can be moved from one port to another, making port licensing

ISL trunking groups

Brocade ISL Trunking is optional software that allows you to create trunking groups of ISLs between
adjacent switches.

If your SAN I/O Module has a Brocade ISL Trunking license, external ports can be used as a
trunking group. Ports that can be used within the same trunking group are color-coded on the SAN
I/O Module’s port side for easy identification.

The external ports are divided into two equal groups:

1. Ports 17, 18, 19, and 20

2. Ports 21, 22, 23, and 0

NOTE

Only the external ports are available for trunking.

The external ports can form 2-port trunks, 3-port trunks, or a 4-port trunk. For details about
Brocade ISL Trunking, see the Brocade Fabric OS Procedures Guide.

at the factory in Access Gateway or Standard Full Fabric Switch mode. (More information on
Access Gateway and Full-Fabric Switch mode is provided in Chapter 2, “Configuring the SAN I/O

Module”.)

• If the part number is DL-4424-0003, then the SAN I/O Module is configured in Access

Gateway mode.

• If the part number is DL-4424-0001, then the SAN I/O Module is configured in Full Fabric

Switch mode. Note that Full Fabric Switch mode is the default factory setting when the
module is licensed for Dual Function mode. With Dual Function mode, you can enable the
module for Access Gateway or Full Fabric Switch mode.

8. For complete instructions to install the SAN I/O Module into the Blade Server Enclosure, refer
to the section on installing an I/O module in the Blade Server Enclosure Hardware Owner’s
Manual.

Cabling guidelines

After modifying the SAN I/O Module’s IP address and domain name (if Module is in Fabric Switch
mode), we recommend that you cable all external ports to fabric connections before bringing the
SAN I/O Module online. Refer to Chapter 2, “Configuring the SAN I/O Module,” for steps on
modifying the IP address.

Begin by cabling ports 17, 18, 19, 20, 21, 22, 23, and 0. Ports 17 and 18 are licensed at the
factory as part of Dynamic Ports On Demand (DPOD). By cabling these ports first, you will not need
to move licenses to other ports you may have cabled.

Connecting the SAN I/O Module to the Ethernet network

Once you have successfully set the appropriate IP address of the SAN I/O Module, you can
establish an Ethernet connection through the Chassis Management Controller (CMC) to a remote
management workstation for any additional configuration. The management workstation must be
on the same Ethernet subnet as the CMC.

NOTE

Ensure that the SAN I/O Module is not being modified from any other connection until configuration
is complete.

Connecting the SAN I/O Module to the fabric

NOTE

Refer to “Cabling guidelines” on page 8 before beginning the following procedure.

Before beginning the following steps, determine whether the SAN I/O Module is in Access Gateway
or Full Fabric Switch mode. This affects the configuration process. Using the SAN I/O Module CLI,
you can enter the ag ––modeShow command to determine the current operating mode.

2

1. If the SAN I/O Module is in Full Fabric Switch mode, continue with step 2 and step 3. If the
Module is in Access Gateway Mode, go on to step 4.

2. Log onto the SAN I/O Module through a Telnet connection, using the admin account.

3. Modify the domain ID if required using SAN I/O Module CLI commands.

The default domain ID is 1. If the SAN I/O Module is not powered on until after it is connected
to the fabric and the default domain ID is already in use, the domain ID for the new SAN I/O
Module is automatically reset to a unique value. If the SAN I/O Module is connected to the
fabric after it has been powered on and the default domain ID is already in use, the fabric
segments.

To find the domain IDs that are currently in use, run the fabricShow command on another SAN
I/O Module in the fabric. Identify an unused domain ID:

a. Disable the SAN I/O Module being configured using the switchDisable command.

b. Enter the configure command.

The command prompts display sequentially. Enter a new value or press Enter to accept
each default value. The SAN I/O Module now has a unique domain ID and can join the
fabric. Following is an example of command output.

Administrator’s Guide. The switchShow, fabricShow, and configUpload commands are
described in detail in the Fabric OS Command Reference Manual.

Changing from Fabric Switch mode to Access Gateway mode

If your SAN I/O Module can run in Dual Function mode and is currently configured in Standard Full
Fabric Switch mode you can enable Access Gateway mode using the following instructions. You can
log into the SAN I/O Module and enable Access Gateway mode using either Web Tools or the SAN
I/O Module command line interface (CLI).

Notes

• The module ships from the factory in either Access Gateway or Dual Function mode. In Dual

Function mode, you can configure the module for either Access Gateway Mode or Full Fabric
Switch mode without an additional license. The module is enabled for Full Fabric Switch mode
as the default. If the module comes configured in Access Gateway mode, you will need an
upgrade license to change to Dual Function mode.

• Enabling Access Gateway mode is a disruptive process because the switch is disabled and

rebooted.Once you enable the SAN I/O Module in Access Gateway mode, only a limited subset
of Fabric OS commands are available and all fabric-related service requests are forwarded to
the fabric switches. See the Access Gateway Administrator’s Guide for more information.

• When you enable Access Gateway mode some fabric information is erased, such as the zone

and security databases. To recover the information save the switch configuration before
enabling Access Gateway mode.

For complete instructions on disabling Access Gateway Mode using the CLI and joining the switch
to the fabric, refer to the “Disabling Access Gateway Mode” section in the Access Gateway
Administrator’s Guide.

Notes

2

• A license is required for Dual Function Mode, which allows you to switch between Access

Gateway and Standard Full Fabric Switch Mode. If your SAN I/O Module was shipped in Access
Gateway Mode, you cannot switch to Fabric Switch Mode without this license.

You can also us e the CLI licenseshow command to determine whether the module is Dual
Function (Switch), or Access Gateway. This command displays current license keys, along with
a list of licensed products enabled by these keys. A Dual Function (Switch) module should have
a “Fabric license” in the command output

• Disabling Access Gateway mode is disruptive because the switch is disabled and rebooted.

Always back up the current configuration before enabling or disabling Access Gateway mode.
Enabling Access Gateway mode clears the security and zone databases. Disabling Access
Gateway mode clears the F_Port to N_Port mapping.

Activating Ports on Demand (POD)

Ports on Demand (POD) licensing allows you to enable up to 24 ports from the initial 12 ports. Add
optional POD licenses using either Brocade Web Tools or a Telnet connection; do not use the Blade
Server Enclosure CMC software.

Ports on Demand is ready to be unlocked in the SAN I/O Module firmware. A POD license might be
supplied with SAN I/O Module software, or you can purchase the license separately from your SAN
I/O Module vendor, who will provide you with a key to unlock it.

Once you have installed the license keys, you must enable the ports. You can do so without
disrupting SAN I/O Module operation, or alternatively, you can disable and re-enable the SAN I/O
Module to activate all ports.

If you remove a POD License, ports that were enabled by that license are disabled.

Chapter

Operating the SAN I/O Module

This chapter describes the operation and interoperability of the SAN I/O Module.

Interoperability

The SAN I/O Module supports interoperability for the following functions:

• link initialization

• principal SAN I/O Module

selection

• routing (FSPF)

• Simple Name Service

• state change notification

Port negotiation

3

• soft WWN zoning

• SNMP facilities

• translative mode (private target support on fabrics)

• trunking (between two Brocade switches)

• Advanced Performance Monitoring

The SAN I/O Module has been designed to be highly interoperable. It supports 1 Gbit/sec, 2
Gbit/sec, and 4 Gbit/sec transmit and receive rates with autonegotiation. The actual data signaling
rate used on a port is automatically sensed and set to the rate supported by the device or devices
attached to the port.

If the SAN I/O Module is connected to a device, but is unable to negotiate the signaling rate, the
operator can manually set the speed of each port through the management interfaces.

The SAN I/O Module is compliant with current Fibre Channel standards, including most
current-generation switch N_Ports, NL_Ports, and E_Ports as well as host adapters, Redundant
Array of Independent Disks (RAID) storage devices, hubs, Fibre-SCSI bridge devices, and older
switch families.

Accessing the SAN I/O Module

The SAN I/O Module is managed as a single element. It has a single IP address and appears as a
separate entity to the Telnet protocol and the Simple Network Management Protocol (SNMP).

When SNMP devices send SNMP messages to a management console running SAN management
software, the information is stored in a Management Information Base (MIB). The Brocade 4424
Fabric OS 4.4.1 supports the FibreAlliance Fibre Channel Management (FCMGMT) MIBs, allowing
the provision of needed information to a SAN administrator.

9.2, 9.3

In addition, the Brocade Fabric Access Layer (API) and the Storage Management Initiative (SMI)
provide facilities for the discovery and management of physical and logical elements in a SAN.
Using the Fabric Access interface to the Fabric OS, a client application can retrieve information and
modify the configuration of Brocade switches in the fabric.

Secure Telnet access is available using Secure Shell (SSH), a network security protocol for secure
remote login and other secure network services over an insecure network.

Brocade Web Tools management is available through a secure browser using Secure Sockets Layer
(SSL). The SSL security protocol provides data encryption, server authentication, message integrity,
and optional client authentication for a TCP/IP connection. Because SSL is built into all major
browsers and Web servers, installing a digital certificate enables the SSL capabilities.

Interpreting POST results

The power-on self test (POST) system check is performed each time the SAN I/O Module is powered
on, rebooted, or reset.

During POST, the LEDs are activated in various indicator patterns.

Perform the following steps to determine POST completion status.

1. Verify that the LEDs on the SAN I/O Module indicate a healthy SAN I/O Module. LED patterns
are described in “Interpreting LED activity,” next.

If one or more LEDs do not display a healthy state, verify that the LEDs are not set to beacon.
Use the SAN I/O Module CLI switchShow command or Web Tools to verify the LED state. For
information about how to turn beaconing on and off, see the Fabric OS Administrator’s Guide
or the Web Tools Administrator’s Guide.

2. Use the Blade Server Enclosure’s Chassis Management Controller (CMC) GUI to verify that the
SAN I/O Module is working correctly.

For details, refer to the Hardware Owner’s Manual for the Blade Server Enclosure.

3. Review the system log for errors.

Any errors detected during POST are written to the system log. Access this log through the
Module’s CLI errShow command. For information about this command, see the Fabric OS

Command Reference Manual. For information about error messages, see the Fabric OS
System Error Message Reference Manual.

Locating the serial number

Before contacting service support, be sure to obtain the module’s serial number. Use one of these
methods to locate the number:

• Use the CLI and enter the ChassisShow command. The SAN I/O Module serial number is

displayed along with other data.

• Locate the serial number on the label attached to the SAN I/O Module. Refer to Figure 3 on

page 5 for location.

Removing and replacing the SAN I/O Module

Complete the following steps to remove and replace a failed SAN I/O Module.

NOTE

Before beginning this procedure, ensure that you have a replacement SAN I/O Module or filler panel
available because you do not want to leave the slot on the Blade Server Enclosure open for an
extended period of time. The slot must be filled with either a replacement SAN I/O Module or a filler
panel to maintain proper airflow.

1. Back up the SAN I/O Module configuration to an FTP server by using the Module’s
configUpload CLI command and following the prompts.

This command uploads the SAN I/O Module configuration to the server, making it available for
downloading to a replacement SAN I/O Module if necessary. It is recommended to back up the
configuration on a regular basis to ensure that a complete configuration is available for
downloading to a replacement SAN I/O Module.

2. Stop all SAN activity requiring the ports used by the SAN I/O Module.

For details about port management, refer to your Blade Server Enclosure Hardware Owner’s
Manual. Verify that there is no activity by viewing the SAN I/O Module LEDs. For details about
LED activity on the SAN I/O Module, see “Interpreting LED activity” on page 22.

3. Remove all cables from the SFP modules.

4. Remove the SFP modules according to the manufacturer’s instructions.

Figure 6 on page 24 details the generic process for removing an SFP from a port.
